I was just wondering if it is possible to bind data using DataBinder.Eval on a html tag with runat=server attribute. For example i want to do something like:
<a href=<%#DataBinder.Eval(Container.DataItem, "file_name") %> runat="server" />
but it doesn't work. does this mean i have to use the asp.net hyperlink control?
I'm having an AJAX Tab Container with 4 tab panels. in my 4th tab panel I'm having 2 panels with 2 div layers.In 3rd panel i'm getting html paypal form code and putting that in session, Then binding the session value to div layer.After the button click was executed. I'm getting error "UnKown RunTime Error" and "INner HTML Error " on debugging. I don't know why is this happening so, can anyone please let me know the correct way.
Below is my code:
<cc1:TabPanel runat="server" HeaderText="TabPanel4" ID="TabPanel4">
<HeaderTemplate>
4. Make Payment
</HeaderTemplate>
<ContentTemplate>
<div>Please click on the below paypal button to complete your payment process.</div>
<asp:Panel ID="pnlDefaultPP" runat="server" Visible="true">
<div runat="server" id="DefaultPP" visible="false">
</div>
</asp:Panel>
<p></p>
<asp:Panel ID="DyPP" runat="server" Visible="false">
<div runat="server" id="paypal" visible="true"></div>
<asp:Button ID="btnPay" Text="Make Payment" runat="server" />
</asp:Panel>
</ContentTemplate>
</cc1:TabPanel>
[Code]....
In the above cs code, if I get promoid, then I'm binding the relative paypal code to div layer. And making the tabpanel4 enabled. When I debug the code, the control is going till tabpanel4.enabled=true, after that I'm getting unknown runtime error or html error.
I'm new to MVC and am trying to create some more user friendly controls for use on the Create views. I'm able to render a control using a combination of extensions and partial views, however I am unable to bind to those controls as I am with the out of the box controls like html.textboxfor such as:
Html.TextBoxFor( model => model.Capability_Menu_Group_Id)
Although the controls renders on the create form, the value is not set on create. I would like to set up this same construct used with TextBoxFor for my custom controls.
Is there any way to bind a datasource to an html select tag with runat=server attribute.
<select runat="server" onchange="showdistrict();" class="textbox" id="DpCity" name="DpCity">
<option value="0">unknow</option>
</select>
What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
I have a list of input type radio buttons in formview (edit mode) and i want to bind data from datasource that is assigned to formview. Can i bind html radio buttons using sql datasource?
View 3 RepliesI am using HTML dropdown list and binding it from ViewData ,but how i can get selected value in controller.
<%=Html.Dropdownlist("ViewDataName")%>
we have define viewdata in controller.it is fetching data in dropdownlist but i am not able to get the selected value so that i can add that value.
let's say we have datatable with "<a>12</a>" as rows.when i try to bind it to gridview programmatically
I'm not getting href links like 12 But just a strings like "<a>12</a>"
Code:
Dim datatable as new DataTable
datatable.Columns.Add("No")
dim datarow1 ad DataRow = datatable.newrow()
datarow1(0) = "<a>12</a>"
datatable.rows.add(datarow1)
gridview1.DataSource = datatable
gridview1.DataBind()
Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back. In my example, I have a Class called "Ingredient" which has 4 public accessories: Name, Barcode, Amount, and Unit.

Or is this not possible? (Basically, I'm trying to re-create a datagrid where certain fields are editable and certain are not...)
I'm getting this message when going to a web app that accesses my service.
"The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8)..."
The thing is, it happens once in a while even when no changes have been made to the service or the web app. And I can make it go away most of the time by going directly to the .svc?wsdl page in my browser and then coming back to the web app.
May I know what is the diffrence between static binding and dynamic binding and which binding is used in
1)Virtual Functions
2)Abstract Class
3)Function Overloading
4)Operator Overloading
5)Fuction Overriding
6)Delegates
The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
.I have a search page where I would search for an item and it would dispaly the results in a gridview...
I have allowed paging and set page size to 10..now I can see the 10 results in the first page and also see the page numbers at the bottom of gridview. But now when i click on the page 2, the method gridview_pageindexchanging is triggered but the result set is not dispalyed. My code is as below..

i understand that the data is not binding in the GridView1_PageIndexChanging method..I do not know how can I make data bind..
I'm trying to build a chart in my application which will act as a client for an ASP.NET 3.5 web service that I created. The error I get is as follows:

View 4 Repliesnot quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:
[code]....
But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.
